UNITED STATES PATENT .OF'FICE.

BOLT-HEAD LOCK AND NUT HOLDER.

Application filed April 6, 1923. Serial No. 830,378.

is to provide a device which can be applied to a' bolt head or nut to hold the same from turnin while a nut is threaded on the belt or the It threaded into a nut. The invention is of particular utility in applying a bolt to parts so located that both ends of the bolt are not accessible at the same time to a workman. In such case my devlce may be applied to the head of the bolt or to a nut on t e bolt which is held from rotating while.

the nut is threaded on the bolt or similarly when the bolt is rotated to thread the same into the nut. A further object of the invention is to provide a device of this kind which is simple in construction, cheap and easy to menu acture.

The invention is illustrated in different .forms in the accompanying drawings, in

which:

Fig. 1 is a rspective view showing the device appli to bolts used for securing beams ther;

Fig. 2 1s a front view of the device made in the form shown in Figure 1;

Figs. 3 and 4 are sectional views, the

former illustrating the device used for holds in the head of a bolt and the latter ho ding a nut; I

Fig. 5 is a perspective view showin a slightly modified form of the device app ied to a railroad rail or similar beam;

Fi 6 is a front view of the form of device illustrated in Figure 5;

Fi 7 and 8 are views of the device illustrate in Figure 5, these views showing different ways in which the device may be made.

Referring to the drawings in detail and particularly to Figures 1 to 4 inclusive, the numeral 10 indicates generally a device embodying my invention. The device as illustrated in these figures is preferably formedof a flat strip of metal, one end of which is bent u to form a wall 11 against which one side 0 the bolt head or nut is adapted to rest. The strip of metal intermediate its ends is for also bent to forms second wall 12 which is spaced from the wall 11 a suflicient distance to permit the head of a bolt or nut to rest between them. The walls 11 and 12 form, in effect, a recess or groove for receiving the head of a bolt or nut. The bottom of this recess is provided with an opening 13 through which the shank of the bolt extends.

The device, as illustrated in Figures 1 to 4 inclusive, is further rovided with an arm or extension 14 whic is of considerable length and which is formed by bending the strip of metal into such osition that the end thereof is in substantial y the same lane as the bottom of the recess between t e walls lland 12. This arm or extension 14, it will be understood, serves to prevent rot movement of the device since it is of suc length as to contact with some portion of the object in which the bolt is being'inserted. For example in the form shown in Figure 1, such arm would contact with a flange or other part of the beam B and thus preventthe head of the bolt from rotating anv considerable distance when the nut is applied to the opposite end of the same, or prevent rotation of the nut when the bolt is threaded into it as shown in Fi re 4.

The form of device illustrated in Figures 5 to 8 inclusive is similar to that already described, being provided with walls 11' and 12 spaced apart to form a recess for receivin the head of a bolt or nut and being provi ed with an opening 13 through which the shank of the bolt extends. In this form of the device the contact arm 14 extends from contact with the flange or head of the rail' to prevent rotation of the bolt when a nut is applied thereto. If desired this form of device ma be provided on its rear face with a fiat sur ace parallel to the bottom of the head or nut receiving recess and such a construction is illustrated in Figure 7. In some cases it may be desirable to bevel or cant the rear face of the device with reference to the bottom of the recess so as to produce a binding effect on the shank of the bolt when the same is drawn ti htly against the device. An arrangement 0 this kind is illustrated in Fi re 8.

eferring to the modifications of my invention shown in Figs. 5 to 8, inclusive, in

these views, I show a lockin device for a bolt and which is particular y suitable for railway use.

In these views, I show a locking device for a bolt comprising a channel portion for engagement with a. bolt head and an arm integral with the channel portion to limit turning movement. The channel portion is comprised by outwardly-extending walls 11 and 12 joined by a bottom or web portion provided with an aperture 13' for the shank of a bolt. 1 a

The arm 14 extends laterally and obli uely with respect to the wall 12 and it is ofl-set outwardly with respect to the bottom of the channel portion. The oblique extension of the arm 14 to a point beyond a transverse plane passing through the adjacent end of the channel portion permits of the H locking device beingemployed in positions aflordlngratherclose clearance while at all times-assuring. a maximum resisting moment to turning. Assumin the device to be placed on the'shank o a bolt and the bolt turnul slightly, the rounded oint of the arm-714' is the first portion 0. the locking device to come in contact with a flange;

The obliqueextension of the arm not only assuresthat the point shall be the first part to contact with afiange, but it also affords a very strong construction in that it prob vides resistance to turnin largely by compression; and to this ,end t e arm tapers outwardly from the wall 12" to assure ample material in compression to afford a good resisting moment. This is particularly important if the locking device is made of for the reason that the cast iron.

By having the arml4'! off-set outwardly from the channel port-ion, it is assured'that the bottom surface of the channel portion shall be firmly positioned against a web snr face and the arm shall'be far enough'out to avoid fillets and obtain a firm seating against a flange. This is particularly advantgeous if the locking device is made of cast iron ossibility of wedg ing against a fillet and possibly cracking owing to deflection is avoided.

It will thus be seen that my invention provides a device which can be easily and quickl applied to the head or nut of a-bolt and w ich willeif'ectively prevent turning of such part whilea nut is applied to the other be end of the bolt, or the bolt rotated into the nut. With my device it is therefore unnecessary for a workman to take hold of both ends of the bolt andthe device is therefore of particular utility where, on account of the strips of metal by merely pressing or stamping the same into the desired shape.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. A non-deformable nut or head lock for a'bolt, which is adapted to extend through the web of a flanged rail or beam comprising a nut or head engaging member havin a depression provided with a bottom sur ace for engagement by the bottom surface of the head or nut and with parallel interior side surfaces for en agement with parallel side surfaces of the end or nut, the bottom of said depression being provided with ana rture to receive the shank of a bolt, an an arm member integral with the nut or head engaging member and adapted to enga. the ange of a beam or rail to limit turning of the head or nut.
